Another feature implemented in Magnum CSG14 Series Converter Switches is a
collision-based flow-control mechanism (when operating at half-duplex only). When the
Switch detects that its free buffer queue space is low, the Switch prevents more frames
from entering by forcing a collision signal on all receiving half-duplex ports in order to stop
incoming traffic.
The latency (the time the frame spends in the Switch before it is sent along or
forwarded to its destination) of the CSG14 Series Converter Switches varies with the port-
speed types. The length of the frame is a variable as it is with all store-and-forward
switches. For 10 Mb-to-10 Mb or 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the
latency is 15 microseconds plus the packet time at 10 Mb. For 100Mb-to-100Mb
forwarding, the latency is 5 microseconds plus the packet time at 100Mb.
